Html 如何添加类标签ul CheckboxSelectMultiple django

我的表格

'warranty': forms.CheckboxSelectMultiple(attrs={'class': 'list-inline'}),

<ul class="MYCLASS" id=id_class>
  <li class="list-inline id="id_warranty_1" name="warranty">opcion 1</li>
  <li class="list-inline id="id_warranty_2" name="warranty">opcion 2</li>
  <li class="list-inline id="id_warranty_3" name="warranty">opcion 3</li>
</ul>

我的模板

<div class="col-md-12" style="height: 50px;  width: 900px;">
   <label class="list-inline col-xs-6" for="{{form2.warranty.name}}" style="width: 140px; padding-right: 20px;padding-left: 20px;">{{ form2.warranty.label }}</label>
   {{ form2.warranty}}
</div>

<ul class="MYCLASS" id=id_class>
  <li class="list-inline id="id_warranty_1" name="warranty">opcion 1</li>
  <li class="list-inline id="id_warranty_2" name="warranty">opcion 2</li>
  <li class="list-inline id="id_warranty_3" name="warranty">opcion 3</li>
</ul>

{{form2.warranty.label}
{{form2.保修}

结果

<ul id=id_class>
  <li class="list-inline id="id_warranty_1" name="warranty">opcion 1</li>
  <li class="list-inline id="id_warranty_2" name="warranty">opcion 2</li>
  <li class="list-inline id="id_warranty_3" name="warranty">opcion 3</li>
</ul>

<ul class="MYCLASS" id=id_class>
  <li class="list-inline id="id_warranty_1" name="warranty">opcion 1</li>
  <li class="list-inline id="id_warranty_2" name="warranty">opcion 2</li>
  <li class="list-inline id="id_warranty_3" name="warranty">opcion 3</li>
